Windows Update Standalone Installer (WUSA) returns 0x5 ERROR_ACCESS_DENIED when deploying Windows Update .msu files through Windows Remote Management 2.0 and Windows Remote Shell. You may also see the following in the Application Event log:
Source: Microsoft-Windows-WUSA
Event ID: 3
Level: Error
Description: Windows update could not be installed because of error 2147942405 "Access is denied."
Installing an update using WUSA or the WUA APIs on a remote machine isn't supported.
To work around this issue, use the following method:
Extract the .msu file through Windows Remote Shell with WUSA using the following command:
winrs.exe -r:<computername> wusa.exe <update> /extract:<destination>
When complete, install the .cab package with dism.exe or Package Manager. To use dism.exe, use the command below:
winrs.exe -r:<computername> dism.exe /online /add-package /PackagePath:<Path_To_Package>\KBnnnnnnn.cab
The Windows Update Standalone Installer uses the Windows Update Agent API to install update packages. Update packages have a .msu file name extension. The .msu file name extension is associated with the Windows Update Standalone Installer.
The security restrictions on remote use of the WUA APIs are documented here:
